For Use with Decks over Concrete Slabs


The Adjustable Joist Support has been designed specifically to enable decks to easily be built over concrete slabs in areas where limited ground clearance is available. It is ideal for use when the step-down from your door to your concrete slab is between 100mm (minimum) and around 230mm (maximum).

The AJ45KIT & AJH45G has been specifically designed to be used with 45mm wide treated pine timber joists and the AJH50G for 50mm wide Steel or Hardwood joists for the Australian & New Zealand markets.

For exact heights please see our “Minimum and Maximum Top of Joists Height information” or “Heights achieved” grid (both listed below) using 60mm,100mm & 120mm M10 bolts and 70,90, & 140 x 45mm Timber joists for the AJ45KIT, AJH45G and using 60mm & 120mm M10 bolts for 100 & 150mm x 50mm Steel or Hardwood joists.
